solved Gif Creation

[Dad72]

In the documentation there is an example to create a gif animation: https://doc.babylonjs.com/how_to/render_scene_on_a_png

 var imgNm = 0;
    scene.render();
    scene.registerAfterRender(function(){
        ground.rotation.y += 1 * Math.PI / 90;
        if(imgNm++ < 90) {
            BABYLON.Tools.CreateScreenshotUsingRenderTarget(engine, camera, 200);
        }
    });

But it does not work at all. This wants to download 90 PNG images instead of a gif image.

I think the documentation lacks information here like a PG that shows how to download a Gif image

PG here: https://www.babylonjs-playground.com/#ZQ1KCR#3

(just a little advice for forum users: do not click on the PG link, you will be asked 90 times by your browser where you want to download each image ? )

And about your issue I'm not sure if it's possible to generate a gif using javascript? In that case, documentation has to be more explicit, saying that gif isn't exported, but that you can generate image frames so as to transform them in gif with your own tools (Photoshop, Gimp, imageMagick, etc)

[Dad72]

Yes,  this is possible with javascript. there are several libs  including : gifshot

I have to modify the PG so that only 10 images (no 90). ?

The documentation says we can generate gif, so I test it and it does not work.

There is an extension that creates animated gifs, but I'm not sure what is the state of the code. Give it a shot if you are willing.

I already have what is needed.I just point out that something in the documentation is not clearly explain.What is explain, does not work, because it certainly lacks more precision to generate a gif image.  I do not ask how to do it.

Look at what is written in the documentation at the bottom of the page.

Maybe an example PG would help, because I find the information very misleading and not complete.

Sure. Please file an issue at https://github.com/BabylonJS/Documentation or better yet, if you feel inclined, open a PR. ?

Thank you but I know the address. I know Babylon since he exists. I am not a newcomer. I'm not going to multiply the reports now that I've done it here, I'm doing it on the forum by habit, and I do not want to make PR not knowing how to edit with proper English. I therefore prefer to abstain and leave those who know how to do it.

We don't track issues in the forums, so it needs to be on GitHub or this may get lost in the wind. I've filed it here: https://github.com/BabylonJS/Documentation/issues/1333

@Dad72 I think that your English is fine, and don' t forget that your PR will be reviewed by someone else, so your English will be corrected if needed then.
There are many people who aren' t native English speakers (including me), and still our documenting effort is worth more than no documentation   !

[Dad72]

@Nodragem, You are right Nodragem. But I do not really like GitHub, so I just post things here and lets do the people that are more competent than me.

But I understand what you are saying. It's just that I'm extremely lazy sometimes, especially during the winters. ?

I preferred the use of the Forum which suits me well and remain a user of Babylon rather than a contributor, even if I sometimes contribute and that it will surely happen again from time to time.

Fixed ?
